ABSTRACT:
In a process and a device for fitting at least one electrically conducting detector wire in a plastic cable duct which can be laid in the ground so that said detector wire is embedded and surrounded on all sides, it is suggested to make a wire-receiving groove in a wall of the duct, then to lay the wire in the receiving groove, and finally to lead a separate, softened filler material into the receiving groove and weld it to the duct wall. In this way, the detector wire is reliably embedded in the duct-wall.
